Four numbers have a median of 4, a mean of 5 and a range of 9. The numbers are not integers. What could they be?

If the numbers in order are A, B, C, D, 4=(B+C)/2, 5=(A+B+C+D)/4, D-A=9.
B+C=8, (A+8+A+9)/4=5, 2A+17=20, 2A=3, A=1.5, D=10.5.
If 4-B=C-4 and B and C are not integers B could be 3.5 and C=4.5.
The numbers could be 1.5, 3.5, 4.5, 10.5.

Answer:

1. 1 < 8

2. 7 > -17

3. n-6 (N could be 7)

4. -4 x 3= -12

5. -5/5= -1 since the sign means greater than or equal to, that could be right.)

6. 3>Z (1) - 1

A researcher wishes to be 95% confident that her estimate of the true proportion of individuals who travel overseas is within 3%

andre [41]

Answer: a) 683 b) 1067

Step-by-step explanation:

The confidence interval for population proportion is given by :-

$p\pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}$

a) Given : Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}}=\pm1.96$

Margin of error : $E=0.03$

Formula to calculate the sample size needed for interval estimate of population proportion :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.2(0.8)(\dfrac{1.96}{0.03})^2=682.951111111\approx683$

Hence, the required sample size would be 683 .

b) If no estimate of the sample proportion is available then the formula to calculate sample size will be :-

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.03})^2=1067.11111111\approx1067$

Hence, the required sample size would be 1067 .
